PROTECTING-COVERING FOR FILES.

Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed June 18. 1907. Serial No. 379.610.

To all whom it may concern:

Be it known that I, CHARLEs W. KENNON, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements inProtecting-Coverings for Piles and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in coverings for protecting thesubmerged portions of piles or other submarine constructions from theattacks of aqueous animal life,

such for instance as the teredo, and the in vention is primarilydesigned as an improvement over the prior patent, No. 587,077, datedJuly 27, 1897, issued to C. WV. Kennon. In that patent the piles werepro tected by means of boards cut from the palmetto tree, which boardswere specifically prepared and were secured to the piles in separatestrips. This arrangement, however, has certain disadvantages, inasmuchas it is more or less difficult to properly set the boards in place sothat the pile is absolutely protected from the attacks of the aqueouslife. By the present invention, however, it is aimed to prepare thefiber of the palmetto tree in such fashion as to make a woven coveringwhich may readily be wrapped around the pile and secured thereto in anysuitable fashion, preventing the necessity of the joinder of severalsections or boards, as described in the patent aforesaid.

In broadly carrying out the invention, the aim is to disintegrate thefiber of the palmetto tree and to weave or to intermesh or intertwinethe individual strands of fiber secured therefrom into an integralcovering or wrapper of fibrous palmetto material, it having been foundthat the properties of the palmetto tree are very high as a repellant toaqueous animal life, and particularly the teredo.

While I do not restrict myself to the exact details illustrated anddescribed, for the purpose of disclosure, reference is had to theaccompanying drawings, showing a'practical ,embodiment of the invention,in which:

Figure 1 designates apile driven in position and showing there around acovering formed of interwoven fibers of the palmetto tree, and Fig. 2 isa view showing a portion of said covering roughly illustrating a methodof securing the individual strands of fiber together.

1 designates the pile and 2 the fibrous palmetto covering which may besecured in position thereon in any suitable way. While the same may beapplied by winding it around the pile spirally, for the purpose ofillustration, in the drawings it is simply shown as being wrapped aroundin a vertical direction, the tops and bottoms being protected, ifdesired, by suitable bands 3. It will be understood, however, that I donot limit myself to any particular method of Wrapping the coveringaround the pile and securing the same thereto. Also it may be observedthat if desirable, the covering may be treated with any suitablecompound be fore being placed around the pile, said compound beingcomposed of properties that are in themselves a protection against theteredo: this being donefor still further protecting the pile and itscovering. I'have found in actual practice, that a good compound'for thispurpose is a mixture of asphaltum, resin, pitch, creosote and oxid ofiron.

In preparing the covering as previously stated, the fiber of thepalmetto tree is separated into individual strands, which strands may-bespun and interwoven in any suitable manner to form the flexiblecovering. In actual operation, this would probably be done by a machine,but for the purpose of illustration in the drawings in Fig. 2, there isshown a plurality of plaits 4, stitched together edgewise, as at 5,which plaits are formed by a plurality of bunches of disintegratedfibers twisted or plaited together.

Having thus described the invention, what I claim is 1. The combinationwith a pile, log or other timber, of a fibrous wrapping made from thepalmetto applied directly to that portion of its surface which is to besubmerged, said wrapping consisting of the individual strands ofpalmetto fiber woven into a material of desired thickness and width,substantially as described.

2. The combination with a'pile, log or other timber, of a fibrouswrapping made from the almetto applied directly to that portion of itssurface which is to be submerged, said wrapping oonsisting of theindividual strands of palmetto fiber woven into A a material of desiredthickness and width, and treated with a teredo, protecting compound,substantially as described.

3. The process herein described of protecting piles, logs etc. andrendering them teredo proof, the same consisting in first disintegratingthe fiber of the palmetto into individual strands, then weaving the saidfiber into a burlap of suitable width and thickness, then applying asuitable com pound to the woven fabric, and finally securing the wovenfabric to the exterior of the pile to be protected by wrapping the samearound it in any suitable manner either spirally or otherwise andfinally securing the fibrous wrapping directly upon the surface of thepile, etc. by any suitable fastening, substantially as described.

4. The process herein described of protecting piles, logs etc, andrendering them teredo proof, the same consisting in first disintegratingthe fiber of the palmetto into individual strands, then weaving the saidfiber into a burlap of suitable width and thickness, then applying asuitable compound to the woven fabric, and finally securing the wovenfabric to the exterior of the pile to be protected, substantially asdescribed.

5. The process herein described of protecting piles, logs etc., andrendering them teredo proof, the same consisting in first disintegratingthe fiber of the palmetto into individual strands, then weaving the saidfiber into a burlap of suitable width and thickness, then applying asuitable compound to the woven fabric consisting of a mixture ofasphaltum, resin, pitch creosote and oxid of iron, and finally securingthe woven fabric to the exterior of the pile to be protected,substantially as described.

In testimony whereof, I affix my signature in presence of two witnesses.

CHARLES W. KENNON.
